The most aperture per euro, and an alignment to keep · review
A 114/500 Newtonian on an equatorial mount, supplied with two eyepieces, a 3x Barlow, an LED red dot finder and a smartphone camera adapter.
The bottom line A fast, wide 114 mm whose real strength is the low-power view, sold with a magnification claim that points the wrong way.
One hundred and fourteen millimetres of aperture against five hundred of focal length is f/4.4. That is fast even by reflector standards, and it has two consequences worth stating plainly: the wide-field view is excellent for the size, and the optical alignment has to be right, because a fast mirror punishes a small error more than a slow one does.
Once the polar axis points at the pole, following a target is one slow-motion control rather than two. The cost is a setup routine before the first object, which is the trade every equatorial mount asks a beginner to make.
Five hundred divided by four is 125x, and with the 3x Barlow the listing reaches its 375x headline. On a 114 mm mirror, that is well past what the aperture can resolve; the image gets larger, dimmer and no sharper. The 20 mm is the eyepiece that will show this telescope at its best.
Open clusters, the brighter nebulae and sweeping along the Milky Way — the targets a wide, fast field suits. The maker’s own bullet says as much before the magnification claim arrives.
German, French, Italian and Spanish Amazon stores ran from 199 € to 206 € on the day of the survey.
British Amazon store lists it in local currency, which the euro range above sets aside.
American Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.

Every Newtonian does, and a fast one shows the error sooner than a slow one. The maker states that both mirrors are adjustable, which is the precondition; a collimation tool is the accompanying purchase.
It comes from the 4 mm eyepiece with the 3x Barlow. The optical ceiling for a 114 mm is conventionally put near twice the aperture in millimetres, and the atmosphere is usually lower still.
130 mm aperture · smartphone sky recognition
A 130 mm Newtonian on a manual alt-azimuth mount whose dock and app read the star field through the phone camera and steer the observer to a target with on-screen arrows.
Best for: A beginner who wants to see things this month rather than learn to star-hop first
